Definition: A weld of approximately triangular cross-section joining two surfaces at right angles or overlapping, commonly used in steel fabrication.
Example in context
“The double fillet weld on both sides of the stiffener plate was designed to develop the full yield strength of the plate.”
“Stifner plakanın her iki tarafındaki çift köşe kaynağı, plakanın tam akma dayanımını geliştirecek şekilde tasarlandı.”
Where engineers use it
Fillet welds are the most common weld type in structural steel fabrication; engineers check leg size, throat thickness, effective length, and orientation relative to applied loads.
Synonyms: fillet welding
Antonyms: groove weld
In Manufacturing Engineering
A fillet weld is a weld of approximately triangular cross-section joining two surfaces at approximately right angles in a lap, T, or corner joint. It is the most common weld type in structural fabrication.
“The engineer specified a 6 mm leg length fillet weld for the bracket to base plate connection to ensure adequate load transfer.”
Practice: can you use “Fillet Weld” at work?
You are inspecting a welded truss connection and find a fillet weld with a leg size 1/8 inch less than specified. How do you determine if it meets the minimum strength requirement?
